Abstract

Cayenne pepper is one of vegetables that is consumed almost every day by every household. However, cayenne pepper is characterized by not being long-lasting, so efforts are needed to extend the shelf life of cayenne peppers. Ecoenzyme is known as a multipurpose solution that has antimicrobial properties, so it is thought that ecoenzyme can be used as a natural preservative, for example to extend the shelf life cayenne pepper. This research aims to determine the effectiveness of ecoenzyme solutions in extending the shelf life of cayenne pepper. The research was carried out using fruit-derived ecoenzyme solution and vegetable-derived ecoenzyme solution, with treatment without dilution, ecoenzyme solutions with a concentration of 75%, and ecoenzyme solutions with a concentration of 50%. The results of the research showed that at full concentration without dilution, fruit-derived or vegetables-derived ecoenzyme solution can extend the shelf life of cayenne pepper to 10 days. It is hoped that these results will be useful for post-harvest purposes of cayenne pepper, both on a household and larger scale.

Abstract

This study aims to compare the biology learning outcomes of students in classes X E4 and X E5 at SMA Veteran 1 Sukoharjo. Sukoharjo (a senior high school). The study used a descriptive quantitative method with an instrument in the form of a multiple-choice biology test consisting of 10 questions. The research sample involved all students in classes X E4 and X E5 in the 2025/2026 academic year, with a total of 76 respondents. Descriptive statistical analysis was conducted to obtain an initial overview of the students' Biology test results, while the prerequisite analysis tests included normality and homogeneity of variance tests. The normality test results showed that the student learning outcome data in both classes were normally distributed, and the homogeneity test results showed that the data variance was homogeneous, thus fulfilling the requirements for an independent two-sample t-test. The t-test results showed a significance value of Sig. (2-tailed) of 0.530 (> 0.05), indicating that there was no significant difference between the biology learning outcomes of students in classes X E4 and X E5 at SMA Veteran 1 Sukoharjo
